Food poisoning is common condition that happens when you eat food or drink water that’s contaminated with harmful bacteria, viruses, or toxins. It can cause unpleasant symptoms like nausea, vomiting, diarrhea, and stomach cramps.
Common Symptoms of Food Poisoning
Symptoms of food poisoning can vary depending on the source of the contamination. However, some common symptoms include:
- Nausea
- Vomiting
- Diarrhea
- Stomach cramps
- Fever

These symptoms can show up within hours of eating contaminated food or may take a day or two to appear. The duration of food poisoning also depends on the type of germ that caused it.

How Long Does Food Poisoning Last?
In most cases, food poisoning lasts for about 1 to 3 days. However, the duration can vary based on the type of contaminant:
1. Bacterial Food Poisoning
Common bacteria like Salmonella and E. coli can cause food poisoning. Symptoms usually last for 1 to 7 days. Listeria, another type of bacteria, can cause symptoms that last for weeks in severe cases.
2. Viral Food Poisoning
Viruses such as norovirus can lead to food poisoning that lasts for 1 to 3 days. These viruses are highly contagious and often spread through contaminated food or water.
3. Parasitic Food Poisoning
Parasites like Giardia can cause longer lasting symptoms, which may persist for weeks or even months if not treated.
4. Toxin Induced Food Poisoning
Some types of food poisoning are caused by toxins produced by bacteria. For example, Staphylococcus aureus can cause symptoms that appear quickly but often subside within 24 to 48 hours.

When to See Doctor
While most cases of food poisoning resolve on their own, some situations require medical attention. You should see a doctor if you experience:
- Severe dehydration (dry mouth, dizziness, or very little urine output)
- Blood in your stool
- High fever (above 101.5°F or 38.6°C)
- Symptoms lasting longer than 3 days
- Difficulty keeping liquids down due to persistent vomiting
These symptoms could indicate a more serious infection or condition that requires prompt treatment.
How to Recover from Food Poisoning
Recovery from food poisoning often involves rest and hydration. Here are some tips to help you feel better:
- Stay Hydrated: Diarrhea and vomiting can cause dehydration, so it’s important to drink plenty of fluids. Water, clear broths, and oral rehydration solutions are good options.
- Follow a Bland Diet: Once you’re able to eat, stick to bland, easy to digest foods like bananas, rice, applesauce, and toast the BRAT diet.
- Avoid Certain Foods: Stay away from dairy, caffeine, alcohol, fatty foods, and spicy foods until your symptoms subside.
- Rest: Your body needs energy to fight off the infection, so take it easy and get plenty of sleep.
- Consider Medications: Over the counter medications like loperamide (Imodium) can help with diarrhea, but consult a doctor before using them, especially if you have a fever or bloody stools.
